HEMP Hardening
High-Altitude Electromagnetic Pulse (HEMP) Design and Testing For MIL-STD-188-125-2 Compliance
Classification of the ECU as Mission Critical Equipment (MCE) which must be located outside of an electromagnetic barrier.
- Hardening of the ECU using "Special Protective Measures" as defined in MIL-STD-188-125-2
- Maximum re-use of proven HEMP-hardened ECU design
- Location of Controls inside EM barrier with appropriate treatment of barrier penetrations
HEMP hardening of MCE, which must be located outside an electromagnetic barrier, is accomplished using "Special Protective Measures" (MIL-STD-188-125-2 Section 4.3.6 and Section 5.8)
Special Protective Measures (SPM) may include:
- Use of good EM-reduction layout and construction techniques
- Linear and nonlinear transient suppression / attenuation devices
- Equipment-level hardening measures
- Use of inherently robust technologies and components
- Cable, conduit and local volume shielding
- Shelter EM barrier Interfaces by fiber optic connection
